School shootings becoming more common

The school shooting at Marjory Stoneman Douglas High School in Parkland, Florida, now ranks among the most deadly mass shootings in American history. With at least 17 dead, the Valentine's Day shooting is worse than the Virginia Tech and Columbine shootings.

Two of the deadliest mass shootings in modern U.S. history happened just 35 days apart in 2017. The Las Vegas shooting at the Route 91 music festival near the Mandalay Bay Resort & Casino on Oct. 1 left 58 people dead and hundreds wounded. Then five weeks later, on Nov. 5, at least 26 people were killed by a gunman at a church in Sutherland Springs, Texas.

News of shooting incidents at everyday places like offices, schools and shopping malls seem to have become numbingly common, and a 2014 FBI study found that the number of mass shootings has increased in recent years.

Police said more than 20 firearms were found in Paddock's hotel room, including some modified to fire like fully automatic weapons. At least 18 more firearms, thousands of rounds of ammunition and some explosives were found at his home in Mesquite.
